I've gone back to the 472.12's AGAIN!
Apparently if you have a GSNYC monitor, dwm.exe is spamming NV service REG queries ~1000 times a second and could use up to 5% GPU usage in certain scenarios (nvidia drivers 511.65 and 511.72)
Load up Process Monitor and see for yourselves ( Gsync Monitors )

Nvidia are looking into it
Yes
It's looking more and more likely that it's Display port/GSYNC related
Scroll down, you'll see more reports of it now, with some saying it uses more cpu cycles than spotify or a browser running

Here's my Brothers PC with the same issue! Two completely different systems, but both GSYNC
*SNIP*
Wrong software man
Use Procmon which gives you an up to date listing of processes polled
Load it up
Click Edit : Clear Display
Scroll down for dwm.exe, if nothing use Clear Display again sometimes it takes a couple of event clears before it floods the window again!
I just did a Process Activity Summary, it showed there were atleast 21,904 registry events compared to any other Windows process. Which is crazy!
Most don't notice it, however it can use up to 5% CPU time even in games which it shouldn't be doing! It uses more cpu time than playing a game with spotify or browsers open in the background .
Not a problem pre 5x drivers
I reckon Nvidia is mining on my GPU!
Apparently! 472.12 doesn't suffer this it seems
NVSlimmer is very convenient for removing the bloat and just installing what you want. I use it everytime.Just did a DDU uninstall to completely wipe all the previous rubbish including any Telemetry/Geforce Experience and then used NVSlimmer to only install the core/driver and physx! Will give Last of Us a test tomorrow
The very first 532.x driver has appeared!

Separate branch but more towards Vulkan development, such as Studio drivers being catered more towards Studio work. All drivers work perfectly in games but in terms of stability they go as follows
1) Studio Drivers
2) Vulkan Drivers
3) Game Ready Drivers
